Here’s the problem I’m having:
I recently got two 60LED 1M strips, and it worked great until I tried them today. Emphasis: this worked fine at one point.
I tried to turn it on this morning, and I’m greeted with a stuck LED (though the LED has since changed positions and also changes colors) and an unresponsive data line.
I double check all of the wiring on my end, and it doesn’t appear to be a problem with any of the solder connections or arduino pins. I was able to verify that pin 12 (the default data pin in the example code) was sending some sort of oscillating signal, confirmed by a noticeable noise when I hooked up an 8ohm speaker between pin 12 and ground.
This happens when I use my battery pack (4xDcell=6v) as well as my power brick (5v), both of which worked before.
I think it’s funny to note that the stuck LEDs occur in approximately the same spot, with minor variation, and that the green light is never activated - only red and blue.
I’m running the example program LedStripGradient verbatim.
Here’s a few images of my setup/what’s happening
And here’s a video. Note, you may have to rotate your eyeballs to see this properly.
The lights turning on/off and flickering is me toggling the power applied to the strip (but not arduino - as it’s powered by my computer’s USB port.)
Has anyone run into this before/have any suggestions as to what to test next?
